IMPROVEMENT IN PORTABLE CHAIRS.

To all whom it may concer-u:

Beit lknown that 1I, GEORGE GARDNER, of Glen Gardner Station, (Clarksville Post ()iice,) in the county of Hunterdon arid State of New Jersey, have invented a new and improved Portable Chair; and I do hereby declare that the vfollowing isa full, clear, and exact description thereof, reference being had to the accompanying drawing forming a part of this specitication.

lThe object oi' this invention Vis to facilitate the packing of chairs for transportation; andto this end,

It consists in a chair composed of a number of pieces of. such shape as to lie flat, or nearly so, when packed, and which are provided with a certain arrangement of such fastenings and -a button on the seat of the chair, whereby the '-button, in locking the seat to lthe back, locks all the principal parts oi' the chair together.

In the accompanying drawing- Figure 1 is a perspective view of a chair constructed according to my invention, showing its seatV slightly raised, in order better to represent the fastenings by which it is secured to the frame; and

Figure 2 is a central section of the saine.

Similar letters of reference indicate corresponding parts in both figures. c

To enable others skilled in the art to make and use my invention, I will describe its constructionv and the manner of attaching and detaching its several parts. The back of the chair, with the back legs thereof, form one piece or sectioib-A, which is provided in front, at the point ot' junction of each `of the side-rails ofthe chair, with a metal 'plate-a, which has an upright dovet-ailed .tongue formed on it, such tongue tapering upward.

Each of the front legs 'B of the chair, with `its sidei'ails, B and B,`braced near their rear ends by acrossbrace, e, form another piece or section.

These two pieces or sections are provided, at the rear end of each of the side-rails, with plates, b, havingfo'rmed in them taper-dovetailed grooves,` which correspond and match with the tongues on the plates lt a of the back, and on the upper portionvof the in- `sideot each of thel fore legs are .tongued plates, c c.

and on their' lower portions are other plates, l d, all

similar to those, a a, on the piece A.

' O is a cross-brace, ou each end of which is a taperdovetail gro'oved plategf, corresponding with one of the taper-dovetail tongues on the plates d.

D is the seat, which has permanently attached to the under side or bottom of its forward portion a rail,

g, on each end of which there is a plate, h, containing a dovetailed groove to match with onegof the tongues c c, and, on the rear of the bottom ofthe seat' is a button, j.

The manner of putting the several pieces together is a`s follows: i

rlhe grooved plate b, on the ends of the rails` B1 B, is slid downward on the taper-dovetail tongues oi' the plates a, provided on the piece A. The grooved plates f on the cross-brace' G are next 4slid on the tongues of the lower plates el, on the front legs ofthe pieces B B. lhe grooved plates h, on the ends of the rail g of the seat, are now slid on the tongues of the' upper plates c on the front legs, and the button j is turned so as to extend under the upper rail of' the back-piece A, and will prevent the pieces from any".

upward movement, andthe tapering forni of the tongues and groovcswill prevent their downward;

movement; consequently they will all be securely locked together.

Io detach the parts for packing, the button has only to-be turned from under the aforesaid rail of the back-piece, and the parts may then be detached from one another in the reverse order from that in which they were attached.

i i/Vhen put together thc several parts securely brace each other, and form a very strong chair,

What I claim as my invention. and desire to secure by Lettersl Patent, is

The arrangement of the several fastenings and the button or bolt j on the bottom, substantially as herein described, whereby the several parts of the chair are locked together by the act of'fastening the seat.
